Olivia Wilde joins Niccol's 'I'm.mortal'

Andrew Niccol's "I'm.mortal" is still casting, but the movie has officially lost its title. It's back to untitled project, but in terms of actors, Olivia Wilde has joined Amanda Seyfried and Justin Timberlake.

The movie is set in a futuristic world in which people stop aging when they hit the age of 25. Time is the most precious currency now, and the rich are immortal. Everyone else is struggling, by the way...

More specifically, the plot follows a ghetto rebel who is framed for murdering a rich dude and goes on the run with a hostage (played by Seyfried). They later discover love is more important than anything...

The Wrap says Wilde will play Timberlake's mother. Also starring is Cilian Murphy, who plays a member of the Timekeepers, an organization controlling time. Vincent Kartheiser has also joined the cast.
